JUSTIN KAY TOLES, OF SAN FRANCISCO, CALIFORNTA.

SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed March 8, 1918. Serial No. 221,333.

To all whom it may concern Be it known that I, JUSTIN KAY ToLEs, citizenof the United States, residing at Ran Francisco, in the county of SanFrancisco, State of California, have invented a new and usefulSafety-Razor, of which the following is a specification in such full andclear terms as will enable those skilled in the art to construct and usethe same.

This inventon relates toa safety razor, and its object is to produce asuperior mounting and operating mechanism for such a razor to enable amotor drive to be applied thereto instead of the ordinary fixed bladesafety razor.

Other objects of the inventon will appear as the description proceeds.

An embodiment of the invention is shown in the drawings in which thesame reference numeral is applied to the same portion throughout, but Iam aware that there may be modifications thereof.

Figure 1 is a longitudinal sectional view of the razor holder showingthe driving mechanism-used therewith,

Fig. 2 is a plan vfew of the razor separate from the handle,

Fig. 3 is anend view of one of the razor blades,

Fig. 4 is a plan view of the razor holding head with the drivingmechanism and razor clamp removed therefrom,

Fig. 5 is a view of the complete razor looking at right angles to Fig.1,

Fig. 6 is an end view of the eccentric pin on the top of the drivingshaft,

Fig. 7 is a side elevation of the driving shaft showing the means forconnecting the shaft in the razor handle to the shaft extending from theflexible cable,

Fig. 8 is a plan view of the bell crank extending from the driving shaftto the Fig. 10 is an end view of the razor blade clamp.

of the, latch 7, which latch is disengaged by the push button 8. Thelatch 7 is held in place by means of the screw cap 9, which cap carriesa spiral spring 10 to hold the latch in engagement with the groovedshaft The shaft 5 is connected in any suitable manner with a flexibleshaft 11 which is driven from any suitable source of power.

At the upper end of the handle there are two forwardly projecting arms12, 13, which are connected by means of a cross piece 14 from which aseries of teeth 15 project to give the usual comb effect adjacent thecutting surface common to safety razors.

The cross member 14 has a longitudinally extending rod 15 placed thereinwhich bears upon two small rollers 16 and 17. The rod 15 is embedded in'the cross member 14 alxwe its diameter so that it cannot be removedtherefrom when once placed in the proper position, and it may be movedlongitudinally about one sixty-fourth of an inch in the actual device.The-handle is provided with two bearings 18, 19 to receive the arms 19,20 of the razor clamp, and which arms. are connected by two cross pieces21, 22. The cross piece 21 has a projecting arm 23, and has an openingto receive the curled over edge 24 of the razor blade 25.

The member 22 is provided with a longitudinally extending roller orhearing bar 26 which bears upon two transversely extending rollers'27,28, and like the roller 15, the roller or bearing bar 26 may be movedlongitudinally about one sixty-forth of an inch. l,

The rollers 16, 17 and 27, 28 are very small and are just loose enoughto permit them to rock as they support the bars 15' and 26 a they aremoved by the knife.

The knife or blade clamp is held in engagement with the blade byvmeansof a screw 29 which has a head 30 threaded thereon which bears upon thearm 23 whenthe clamp is to be placed into position against the knifeblade.

The screw 29 is pivotally supported by means of two lugs 31, 32 whichproject from the handle 1 at the opposite side from the arms 12 and 13.blade is a bell crank or L-shaped lever33, which is pivotally mounted toa screw 34, and it has a collar 35 to increase the bearing Immediatelyunder the,

area upon the razor blade. One arm of the bell crank engages theeccentric pin 36 on the top of the shaft 2 and receives motiontherefrom.

In order to protect the face, there are overlapping end pieces 37, 38 atthe ends of the razor blade which cover the corners of the razor andprevent it from touchingthe face at those points.

In operation the shaft 11 receives power from any suitable source,preferably a small high speed electric motor. and as the shaft 2 israpidly rotated the razor blade is rapidly longitudinally reciprocatedthereby improving the cutting effect. The position of the clamp is suchthat the Made is drawn down into close contact with the comb points 15and cannot injure the face, and the bearing of the knife blade upon thebars 15' and 26 does not prevent its movement since they are supportedupon roller bearings for longitudinal movement.

Having thus descfibed my invention what I claim as new and desire tosecure by Letters Patent of the United States is as follows, expressreservation being made of permissible modifications:

1. A safety razor comprising a handle, a

razor comb carried thereby, a razor blade, a clamp pivotally'mounted onthe handle and having a bearing on which the razor blade is movablelongitudinally, rollers to support said bearing, means to hold the bladeWith its cutting edge in close proximity to its comb, and means toreciprocate the blade longitudinally.

2. A safety razor comprising a handle, a razor comb carried thereby, arazor blade, a clamp pivotally mounted on a movable pair of rods oneover the blade and the other under it for holding it with its edge inclose proximity to said comb rollers on which said rods are movablelongitudinally, means to reciprocate the razor blade longitudinally, anda screw at the back of the clamp for adjusting the pressure of theblade.

In testimony whereof I have hereunto set my hand this 2d day of Jan, A.D. 1918.

JUSTIN KAY TOLES.
